A muon collider would enable the big jump ahead in energy reach that is needed for a
fruitful exploration of fundamental interactions. The challenges of producing muon collisions …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

Detector and event visualization are essential parts of the software used in high-energy
physics (HEP) experiments. Modern visualization techniques and multimedia production …

A bstract This document aims to provide an assessment of the potential of future colliding
beam facilities to perform Higgs boson studies. The analysis builds on the submissions …

Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up
approach, whereby the community is first invited to submit proposals (also called inputs) for …

A bstract In this work we revisit the existence of a strong first order electroweak phase
transition (SFOEWPT) and recent m W precision measurement in the Type-I and Type-II …

HEPfit is a flexible open-source tool which, given the Standard Model or any of its
extensions, allows to (i) fit the model parameters to a given set of experimental …

A bstract The “Cabibbo Angle Anomaly”(CAA) originates from the disagreement between the
CKM elements V ud and V us extracted from superallowed beta and kaon decays …

A bstract We present a model of radiative neutrino masses which also resolves anomalies
reported in B-meson decays,\({R} _ {D^{\left (\ast\right)}}\) and\({R} _ {K^{\left (\ast\right)}}\), as …
